330 FUNGUS-FLOEA. 



Growing on Busaula adusta and B. foetens. 

 Gregarious or oaespitose. The conidia produced by the 

 hyphae of the pilaus are large, elliptical, and smooth. 



Nyctalis asterophora. Fr. (fig. 5, p. 301.) 



Pileus about ^ in. across, fleshy, conical then hemispherical, 

 flocculose and rather mealy owing to the large, stellate 

 conidia, whitish then tinged with fawn-colour ; gills adnate, 

 distant, narrow, rather forked, straight, dingy ; stem about 

 -J in. long, slender, twisted, stuffed, white then brownish, 

 rather mealy ; spores elliptical, smooth, 3 x 2 /x,. 



Nyctalis Asterophora, Pries, Hym. Eur., p. 463 ; Cke., 

 Hdbk., p. 344; Cke., lUustr., pi. 1132b. 



Growing on old blackened specimens of Bussula nigricans. 



Gregarious or slightly caespitose. The very lai'ge stellate 

 bodies borne by hyphae on the upper surface of the pileus 

 have been shown by Brefeld to be true conidia, which, under 

 proper cultivation, give origin to the fungus. 



II. SPELEAB. 



Nyctalis caliginosa. W. G. Sm. 



Pileus about i in. across, very fleshy, margin involute, 

 slightly exceeding the gills, marked with light and dark 

 grey colours when wet, white and floccoso-pruinose when 

 dry; gills decurrent, thick, branched; stem, about 2 in. 

 long, floccoso-pruinose, base naked ; spores elliptical, smooth, 

 4 X 21 /.. 



Nyctalis caliginosa, W. G. Smith, Journ. Bot. 1873, p. 337 ; 

 Cke., Hdbk., p. 343 ; Cke., lUustr., pi. 1132a. 



On ground in a dark place, among fallen leaves. 



Odour and taste rank and disagreeable, like Polyporus 

 sguamosus. (W. G. S.) 



Caespitose; stem brown inside, white externally, much 

 swollen at the base, where several are usually more or less 

 grown together. 



A doubtful species. Probably a diseased state of some 

 Glitocyhe. (Cooke.)
